How To Render
Before you start
Before you start you will need to consider the following?
- What is the surface being rendered?
- What thickness will the render need to be applied for the desired finish?
- How do you want to apply the render, either by trowel or roller?
- What sort of finish do you want to achieve either a smooth fine coat or a sandy finish?
Use a Dunlop Multipurpose Acrylic Render as a base coat and then use the Dunlop Multipurpose Fine Coat Render or Dunlop Ready-to-Go Render as a finishing coat.
Ensure the surface is in sound and clean off dust and any contaminating materials or coatings.
If the surface is dry or porous, dampen the surface to be rendered by brushing or sponging the surface or applying a light mist spray of water to prevent rapid drying of the render.
Dense concrete surfaces will require priming with Dunlop Primer and allow to dry for 30 minutes prior to the application of render.
Jointing all FC sheets and blueboard should be carried out as per manufacturer’s instructions.
Mix the Dunlop Acrylic Render as per the water ratios as specified on the packaging.
Apply with a steel trowel, evenly spreading the mix over the surface.
Use a straight edge to ensure that the render is level.
After 10 to 30 minutes, use a plastic trowel to create a smooth surface. The surface is ready for finishing when there is no transfer of render to the fingertips.
For finishing use either a wooden or plastic float for a dense and smooth finish or use a sponge to achieve a coarse and sandy finish.
For the final finishing select either the Dunlop Multipurpose Finecoat Render or the Dunlop Ready –to-Go Render by applying by a steel trowel.
Using either a plastic float or sponge create the desired finish. Watch our Finishing Tip video to create the look you want.
A decorative paint can be applied once the render has cured for 24 hours for each 2mm thickness of render.
- Keep mixed material out of direct sunlight to extend the pot life of the mix.
- Never add additional water to reinvigorate a mix, this could result in the render shrinking and cracking.
- Always wash tools in clean water before the material dries.
